Hello,

I got a loan of some ATPL notes and i'm just trying to understand the concepts of great circle v rhumb line tracks etc.

When you have your Initial track and you use the formula (change of long X sin mean lat) to find convergency, the part thats failing me is the understanding on whether to add the convergency to the initial track to find the final track or subtract convergency to find the final track....

Have i missed something?

Thanks in advance,
